NOTES!
①
Use copper wire only as unit’s power cord. Operating temperature should be within its rated
value.
②
If the length of power cord is more than 15 m, please increase properly the sectional area of
power cord to avoid overload, which may cause accident.
③
Above selection requirements: Power cord size is based on BV single-core wire (2~4pc) at 40
℃
ambient temperature when laying across plastic pipe. Air switch is D type and used at 40
℃
. If
actual installation condition varies, please lower the capacity appropriately according to the
specifications of power cord and air switch provided by manufacturer.
④
Install cut-off device near the unit. The minimum distance between each stage of cut-off device
should be 3 mm (The same for both indoor unit and outdoor unit).
